Can somebody explain what is meant by :
Note: This release includes enhanced security measures that disable insecure access to the hub from outside local network using port forwarding or similar means. No IOT device is meant to be accessed publicly, and our hub is no exception. Use Hubitat Remote Admin, a private VPN, or other secure means of access instead.
I mean, when port forwarding is used, actually an internal IP is accessing the Hub on behalf of the external user.
So if you do not block access to port 443 , you can not block port forwarding.
So what's new with this block ?
